When designing materials and structures at the nanoscale, it is important to be able to characterize and measure them. Getting tools to measure on these very small length scales can be challenging as ...

(Nanowerk News) More than a decade ago, the frequency comb technique was developed at the Max Planck Institute of Quantum Optics by Professor Theodor W. Hänsch. The new tool has stimulated fundamental ...

(Nanowerk News) Devices that use light to see objects, such as microscopes, have a fundamental limitation based on the laws of physics, which is their resolving power. The smallest distance that ...

Just as a meter stick with hundreds of tick marks can be used to measure distances with great precision, a device known as a laser frequency comb, with its hundreds of evenly spaced, sharply defined ...

Scientists from the Faculty of Physics, the Lomonosov Moscow State University, under the guidance of Professor Michael Gorodetsky, in cooperation with colleagues from Swiss Federal Institute of ...

Just as a meter stick with hundreds of tick marks can be used to measure distances with great precision, a device known as a laser frequency comb, with its hundreds of evenly spaced, sharply defined ...

A paper published by Swinburne University of Technology shows how a kind of "optical ruler," or frequency comb, can greatly increase bandwidth in today's data-saturated world. Integrated optical ...

Figure: Octave spanning frequency comb generation in a microresonator. Panel (a) shows the experiment with a glass nano-fiber and a silicon chip with optical resonators. A scanning electron microscope ...
